Hmm...aside from me saying "take that engine out and I'll trade you" ;) I really wouldn't know as you have the DOHC PGM-Fi motor that we all really want.

Don't worry, we'll fix ya up.

May need to start with the basic lowering of the idle mixture screw, the screw right above the throttle body. No check engine lights are on?

i can not fix the idle, sometimes is 900 rpm sometimes increase to 2300 rpm very quicly

if idle jumps up and down that hight, you may have some problems with one of your sensors.
i don't know how to check on B20 but look under the driver seat and see if you can find ECU with blinking light (my luck it won't be there).
